中国地质调查局：湖北水月寺幅（H49E005013）1∶50000地质图数据库

湖北省1:5万水月寺幅(H49E005013)地质图数据库是按照《区域地质调查技术要求(1∶50 000)》(DD 2006–XX) 和地质行业的统一标准及要求，在充分利用已有资料的基础上， 采用数字填图系统(DGSS) 进行野外地质填图及数据库建设，通过野外调查最终绘制成图。通过地质填图和调研，建立完善了调查区多重地层划分与对比系统，解体了元古代地层原黄凉河岩组；新发现一套中太古代磁铁石英岩（变质锆石年龄2.89Ga）及古太古代地质实体（3.3GaTTG，命名为林老爷河片麻岩）；确认野马洞岩组属太古代早期绿岩带的残留，首次获得3.0Ga±、2.93Ga±的两期变质事件年龄，提出扬子陆块与全球板块构造启动时间（3.0Ga）一致性的认识；将区内地质构造演化划分为三个阶段，识别出五个变形期次的构造运动，对区内褶皱、断层和韧性剪切的特征进行了系统总结；简要总结了区内矿产资源、灾害与旅游地质特征。图幅充分反映了1:50 000区域地质调查基础性成果，对扬子陆核黄陵地区早前寒武纪地质构造演化研究具有重要意义。

The 1:50000 geological map database of Shuiyusi Sheet (H49E005013) in Hubei Province was constructed in accordance with the Technical Requirements for Regional Geological Survey (1:50000) (DD 2006–XX) and unified standards of the geological industry. Based on full utilization of existing data, field geological mapping and database development were carried out using the Digital Geological Survey System (DGSS), and the final map was compiled through field investigations.

Through geological mapping and research, a comprehensive multiple stratigraphic division and correlation system for the survey area was established, and the original Huanglianghe Formation within the Proterozoic strata was resolved and reclassified. A suite of Mesoarchean magnetite quartzite (with metamorphic zircon age of 2.89 Ga) and a Paleoarchean geological entity (3.3 Ga TTG, named as Linlaoyehe Gneiss) were newly discovered. The Yemadong Formation was confirmed to be a remnant of the Early Archean greenstone belt. For the first time, two phases of metamorphic event ages of ~3.0 Ga and ~2.93 Ga were obtained, and the viewpoint that the initiation time of global plate tectonics is consistent with that of the Yangtze Continental Block (3.0 Ga) was proposed. The geological tectonic evolution of the area was divided into three stages, five tectonic movements of different deformation phases were identified, and the characteristics of folds, faults and ductile shear zones in the area were systematically summarized. The characteristics of mineral resources, geological hazards and tourism geology in the area were briefly summarized.

This map sheet fully reflects the foundational achievements of the 1:50000 regional geological survey, and holds great significance for the study of the Precambrian geological and tectonic evolution of the Huangling area in the Yangtze Continental Nucleus.
